No matter what I do, I can't seem to make any changes to the processing source that will get built. I've tried adding System.out.println()s, changing error strings, commenting out the bodies of critical methods, introducing uncaught null pointer exceptions, commenting out entire source files, and starting over with a fresh copy of the source several times. Every time, it builds and runs without a hitch, as if my changes were never made. I'm following the build instructions exactly.

The weird thing is that I've managed to do this successfully before, back in December, when I was fooling around with adding Java 5 support to the grammar. Worked fine then. Has something in the build process changed recently, that hasn't been added to the build guide?

I'm using OS X 10.5.7.
